Improvement in blind-fasteners



CHARLES E. STRUCK, 0El NEW N. Y., ASSIGNOR TO HIMSELE AND JAMES TWAMLEY, OF SAME LAGE.

Letters Patent No. 103,795, dated lling] 3l, 1870.

IMPROVEMNT IN BLIND-EASTENERS.'

The Schedule referred to in these Letters Patent and making part-of the same To all 'whom 'it may concern:

. purpose have been devised, but in all cf them known to me, there is either the objection of too great cost,

too much complication of mechanism, or difcnlty of application, and liability to dexaugenient from the shrinking or sagging of the shutter.

' My invention has for its objects to provide a simple and economical appliance, which can be readily put onto nii ontside blinds, and which will be effectual in its operation, and not liable to derangement from the sagging or shrinkage of the shutter; and to these endsr My invention consists in a metallic plate or frame, adapted to lit on and interlock with one-half of the ordinary sliutterhinge, and provided withaJ weighted vibratory latch, and a permanent stop, between which latch and lug the movable portion of the hinge is confined when the shutter is open, substantially as here inaftcr more'fully explained; 'and My invention further consists in the employment, in connection with such a metallic pla-te, ot'- a swinging latch, for clamping or holding themovable parir of the hinge when the blind is closed in or shutT as will be hereinafter more fully described.'

To enable those skilled inthe art todrnake and use my invention, I will proceed to describe the construction and operation of my improved apparatus, referring by letterato the accompanying drawing, in which Figure l is an elevation of one. of my improved blind-fasteners, shown as applied to the hinge of an ordinary outside blind. The blind and window-trame are only shown to a. sufficient extent to illustrate clearly the applicationof my invention.

`Illignre 2 is a top view of the same.

Figure 3 is an elevation or view, hooking at thc outer edge of a window-frame.

Figures 4 and 5 are side and bottom views offthe fastening device, detached from the blind and adapted lfor application tothe opposite side to that in which the device is shown in other figures.

In the several iigures the same part will be found designated by the same letters of reference. A illustrates a portion of the frame of a window; and I .cnrs when the shutter is wide open.

B, a portion ot' an ordinary outside blind or shutter.

(list-he moving halt' oi an ordinary shntter-hinge, or that half which is attached to the blind; 'and .D is the stationary half, or that portion of the hinge Awhich is fastened tothe frame A of lthe window.

E is the body oi' the fastening device, which is in the form (shown)of a metallic plate, having a hole, S, in it (see iig. 5) through which is passed the stud or spindle of'the hinge.

This plate E has two lugs, c p, projecting downward from its lower side, which are designed to straddle the `body of the lower portion Dot' the hinge, as clearly shown, and

It has also two other lugs f j, projecting downward from its lower side, as shown, between which' is hung on a pivot the latch g g2, which is made of the 'shape seen, its'lower endg2 being made sufciently heavyto insure the retention of the latch in the proper position, and its upper portion being so formed (with an inclined edge) that the bottom edge of the shutter can freely ride over it.

M is a stop, projecting up from the body or plate E, and which is designed to operate in conjunction with the catch g to retain or lock the shutter in place. Y

vVhen open at iigs. 1, 2, and 3, I have shown the apparatus vprovided with means for locking the shutter when closed, consisting of "a bolt, N, which-works np .and down through a hole in the plate E, and which is moved by one end of a lever, l, to which it is pivoted, which lever is pivoted to the frame of the window, and is provided at its inner endwith a knob or button, k, by means of which it can be conveniently handled.

The operation of the apparatus may be thus explained:

When the shutter the portion C of hinge-rides over the inclined (upper) edge g of the latch, depressing'it until the'said portion C of hinge comes against the stop M,.which cc- As soon asl the hinge strikes the stop M, (it has passed now clear over the latch g,) the end g of the catch ilies up by reason of its weighted end g2 turning it on its axis, and the body of hinge Gis confined or retained between the latch g and stop M, asclearly shown.

When it is desired to close the shutter, theweighted end ylofthe latch must be raised to depress the outer end g, and permit the hinge (l to pass o`ver it. As the blind is closed, the portion O o f hinge strikes against and'rides over the upper (inclined) end of the vertical bolt N, which is thus depressed, and which rides or is thrown up by the gravity of the heavier end and knob k, and locks oir-secures the blind in its closed condition. l

When it is desired to open the shutter again, the

B is opened, the lower edge oi"- bolt N is thrown down by raising theI knob k, and, as

` the shutter is thrown back, it is automatically locked hack, as before explained.

It will be seen -that the portion C. ot' the hinge is retained or'conined betweenrthe back edge of latch g and the face of lng M, and that, as only a sufiicient play is necessary to insure the free movement of the said'latch g, the said hinge portion will be so steadily and closely held that little or no motion is permitted to the blind, and that, therefore, there will be no noise or rattle ofthe blind when the wind blows, nor can there be any momentum to strain or break the fastener, which, can, therefore, be made very light and cheap. v

For ordinary purposes, and where a hook or other device is used to lock the shutters when closed, the

` iixture may be made, as shown at gs. 4 and', so as to perform only the functions'oll a device for locking the shutter when opened or thrown back.

' By making the fastener with a hole, S, adapted to receive the `shanks or spindle of the hinge, and with was cahility to the hinge in substantially the manner A' shown, which is the main feature of my invention.

It will be understood that the shape and size of the fixture may be varied to suit the shape and sizes of hinges; used, 'and that either or both of the latches or bolts may be used,.tho ugh for a cheap manufacture and an article'y for common or general use, such as seen at igs. 4 and-5, and adapted merely to othel purpose of holding the blind open, and as a substitute for all sorts of fixtures applied tothe wall of the house, is most desirable. y

vHaving explained my invention, so that one skilled in the art can make and use my improved blind-{ixture,

What I claim as new, and desire to secure by Letters Patent, is 'l A blind-fastener, adapted to interlock with or between the halves of the hinge, by passing overthe pintle, and being secured by lugs to the blade of onchalf ofthe hinge, and provided with a permanent stop and swinging latch for locking the blind when open,

as set forth.

Also,vin combination with such a fixture, a bolt, fol' securing the shutter when closed, arranged and opened as described.-

' In testimony whereofl have hereunto set my hand
